search_mtsta: Search for Matching Species Names in the Red List of Montane Tree Species of the Tropical Andes

Description

This function searches for matching species names in the Red List of Montane Tree Species of the Tropical Andes (mtsta package) based on a provided list of species names. The function performs approximate matching using the Levenshtein distance algorithm to find similar names within a specified maximum distance.

Usage

search_mtsta(splist, max_distance = 0.1, ...)

Value

A data frame with the following columns:

• name_submitted: The submitted species names.

• name_matched: The matched species names from the mtsta data.

• accepted_name: The accepted scientific name of the matched species.

• accepted_family: The accepted family name of the matched species.

• accepted_genus: The accepted genus name of the matched species.

• taxonomic_status: The taxonomic status of the matched species.

• iucn: The conservation status of the matched species according to the IUCN Red List Categories.

• distribution: The distribution range of the matched species.

• unsure_distribution: Information about the uncertainty in the distribution data.

• elevation: The elevation range where the species is found.

• assessor: The person or group responsible for assessing the species.

• description: Additional information or description of the species.

• distance: The Levenshtein distance between the submitted name and the matched name.

If no match is found, the name_matched column will contain "nill", and the other columns will be empty.

Arguments

splist

A character vector containing the species names to be matched.

max_distance

The distance used is a generalized Levenshtein distance that indicates the total number of insertions, deletions, and substitutions allowed to match the two names. It can be expressed as an integer or as the fraction of the binomial name. A value between 0 and 1 will be treated as a percentage of the string length. A value greater than 1 will be treated as an absolute number of allowed changes. For example, a name with length 10, and a max_distance = 0.1, allow only one change (insertion, deletion, or substitution). A max_distance = 2, allows two changes.
